Understanding the geometric properties of quantum states and their implications in fundamental physical phenomena is a core aspect of contemporary physics. The quantum geometric tensor (QGT) is a central physical object in this regard, encoding complete information about the geometry of the quantum state. The imaginary part of the QGT is the well-known Berry curvature, which plays an integral role in the topological magnetoelectric and optoelectronic phenomena. The real part of the QGT is the quantum metric, whose importance has come to prominence recently, giving rise to a new set of quantum geometric phenomena such as anomalous Landau levels, flat band superfluidity, excitonic Lamb shifts and nonlinear Hall effect. Despite the central importance of the QGT, its experimental measurements have been restricted only to artificial two-level systems. Here, we develop a framework to measure the QGT in crystalline solids using polarization-, spin- and angle-resolved photoemission spectroscopy. Using this framework, we demonstrate the effective reconstruction of the QGT in the kagome metal CoSn, which hosts topological flat bands. Establishing this momentum- and energy-resolved spectroscopic probe of the QGT is poised to significantly advance our understanding of quantum geometric responses in a wide range of crystalline systems.

Plus, perhaps the biggest complexity of all is that the currency rates are often not free, particularly if you want "live pricing" (updated every few seconds), and particularly if it's for commercial use. And, the fact that they may or may not be free, also illustrates well the fact that there are no definitive rates, there are only "rates according to X".

I was a 90s kid, still just young enough to have my parents tell me to go get out a paper dictionary when I asked "what does this word mean?" It's amazing how much better it "sticks" when you have to stop, get up, open a book, and find the entry.

With a minimal vim setup, I find that I just know Linux, the language intricacies, and the codebase better than my coworkers – not because I'm smarter but because I have to manually look up things I don't know. It's slower in the moment but over time it is much, much faster.

For the same reason, I never copy/paste code that I could not have written from memory.
I suspect many commentators would say the same thing to the English majors out there who were told that passion and a college degree would lead to economic mobility and not a load of debt. Weren’t they also harboring unreasonable views that were not 100% of their own creation?
Some interesting commentary from the lead researcher:

Kang stresses that the new ability to measure the quantum geometry of materials "comes from the close cooperation between theorists and experimentalists."

The COVID pandemic, too, had an impact. Kang, who is from South Korea, was based in that country during the pandemic. "That facilitated a collaboration with theorists in South Korea," says Kang, an experimentalist.

The pandemic also led to an unusual opportunity for Comin. He traveled to Italy to help run the ARPES experiments at the Italian Light Source Elettra, a national laboratory. The lab was closed during the pandemic, but was starting to reopen when Comin arrived.

He found himself alone, however, when Kang tested positive for COVID and couldn't join him. So he inadvertently ran the experiments himself with the support of local scientists.

"As a professor, I lead projects but students and postdocs actually carry out the work. So this is basically the last study where I actually contributed to the experiments themselves," he says.

The Gotthard tunnel is also in Europe and some kilometers longer than the Channel tunnel. I think that one has security checks and the other not has nothing to do with one being under water and the other under rock. I'd be very surprised if their security measures will not harmonize in the long run.
My first immediate reaction was that it is awful, but I'm not sure actually, I think I can get used to it. The only real UX "bugs" I found so far:

- the frontpage for Vault no longer shows the categories (Login/Card/Identity) you have to use filter now for that (= +2/3 more clicks)

- when you search something there is no way to "go back" or clear the search, you have to manually clear the search text from the input field

More design related:

- the new "compact mode" should probably be the default and it also should decrease the font size (although you can just zoom-out)

Also I think some user complains where already addressed via settings, in Appearance you can switch on "Compact Mode" (also you should zoom in once more Ctrl+Minus once or twice) and turn on "Show quick copy actions on vault".

I think you two are talking about different things. The AI winter as I understand it refers to slowing technological advancement in “expert systems” for example. But technological development is moving faster than ever.

This is different. It’s a weird combination of huge amounts of capital chasing a very specific idea of next token prediction, and a slowdown in SWE hiring that may be related. It’s the first time “AI” as an industry has eaten itself.
That seems unlikely given that the full HBM supply for the next year has been earmarked for enterprise GPUs. That said, it would be definitely nice if HBM became available for consumer GPUs.
I think you are imagining a different class of "questions".

To clarify, I was doing research on applied math. My field is not analysis, but I needed to prove some bounds on certain messed up expressions (involving special functions, etc), and analyze an ODE that's not analytically solvable. I used the COT model a fair bit.

I would ask ChatGPT for hints/ideas/direction in proving various bounds, asking it for theorems or similar results in literature. This is exactly the kind of thing where a researcher would go "yeah this looks like X" or "I think I saw something like this in (book/article name)", or just know a method; or alternatively say they have no clue. ChatGPT most often will confidently give me a "solution", being right 10% of the time (when there's a pretty standard way to do it that I didn't see/know).

On the whole it was quite useful.

Okay, so a web search and some looking around gives me https://www.honeycomb.io/frontend-observability. I guess this is something to do with tools for sending telemetry back from web applications and then doing statistics on them and giving the user some nice reports.

"Observability" seems like a weird term for that to me, but okay.

But I don't understand why not just give the appropriate context in the submission, rather than keeping a title that only makes sense to a very specific niche audience and then not saying up front what the niche is.

The concept of an "event" is coherent in many other programming contexts, so the possibility that one could be coherently "wide" is at least plausibly interesting. But then I get there and find myself completely disoriented, and eventually figure out that it's not actually relevant to anything I do. And anyway it looks like a lot of this jargon is really just not necessary to convey the core ideas... ?
I haven’t been able to replicate the claim that it’s “better than Claude 3.5 by a wide margin.” In my experience, they’re often quite comparable and deliver similar results about half the time.

We (or I, at least) aren't asking Joe Blogman to host his own site (though if he does, I'll cheer them on just the same). We're asking other, bigger sites, the ones that large groups of people visit, to avoid Cloudflare. These tend to be the "infrastructure" websites; the ones that, if you can't access them, you have a harder time that day because you have an actual task you have to do - and the company behind the website that Cloudflare is blocking you from, has reduced other avenues of completing the task because "customers can use the website".

It is in this way that Cloudflare is bad. It's bad for consumers being blocked because Cloudflare doesn't like their browser, IP, or local weather (because who the hell knows exactly why they're being blocked), and it's bad for businesses too: both competing CDNs that can't compete with CF's scale, and businesses that rely on CF but will be hit with a monopoly-sized price increase once Cloudflare's competition is extinct.

Standardization will be great... for 1-2 years.

After that, you'll start losing out on lost innovation that wasn't allowed to happen.

"Dozens of companies independently spending millions solving the same problems" only seems wasteful if you don't think about this in terms of at least a couple of steps of game theory. Competing co's come up with a variety of different solutions, leaving us in a more robust state with lots of different options.

I'm interested in trying this out and started to go through the login flow for youtube, for some reason it opens in a tab within the Grayjay app which then means I can't use Google's passkey auth, and something is even preventing me from copy/pasting my Google password in from my password manager (it's too long for me to want to type out just to try the app.)

Gentle feedback to open the auth flow in the default browser, might make things easier.

Okay, but... as opposed to what? And why is it better this way?

>“Event” is an over-loaded term in telemetry so replace that with “log line” or “span” if you like. They are all effectively the same thing.

In the programming I do, "event" doesn't mean anything to do with logging or telemetry.
I meant this in the general case, not specifically binary addition. Also, returning an token by ChatGPT is technically an O(1) operation, so the same principle applies. Returning a computation answer of O(n_required_tokens) cannot be delivered in O(1) time without some sort of caching.
> these numbers are just your perception.

Of course they are, I hoped it was clear I was just sharing my experience trying to use it for research!

I did in general word it as I would a question to a researcher, which includes an uncertainty in it being true. E.g. this is from a recent prompt: "is this true in general, if not, what are the conditions for this to be true?"

those "affected" have the same little compassion towards many millions of others who are not lucky to work on AI in top school and visiting top AI conference. That's what makes them entitled.

> When you get good enough at mathematics, you can tell if your proofs are correct or not without asking a TA to grade them for you.

This is simply not true - you can get a very good sense of when your argument is correct, yes. But having graded for (graduate, even!) courses, even advanced students make mistakes. It's not limited to students, either; tons of textbooks have significant errata, and its not as if no retraction in math has ever been issued.

These get corrected by talking with other people - if you have an LLM spew out this synthetic chain-of-reasoning data, you probably get at least some wrong proofs, and if you blindly try to scale with this I would expect it to collapse.

Even tying into a proof-checker seems non-trivial to me. If you work purely in the proof-checker, you never say anything wrong - but the presentations in proof checking language is very different from textual ones, so I would anticipate issues of the LLM leveraging knowledge from, say, textbooks in its proofs. You might also run into issues of the AI playing a game against the compiler rather than building understanding (you see elements of this in the proofs produced by AlphaProof). And if you start mixing natural language and proof checkers, you've just kicked the verification can up the road a bit, since you need some way of ensuring the natural language actually matches the statements being shown by the proof checker.

I don't think these are insurmountable challenges, but I also don't think its as simple as the "generate synthetic data and scale harder" approach the parent comment thinks. Perhaps I'm wrong - time will tell.

This is a tough question to answer in detail: I encourage you to browse yourself. (They are all on Github) but: The BF code base in itself isn't too bad. The AP one is very complicated, and difficult to navigate. The names and organization are confusing. Compiling is finicky and slow due to the tool system they use, and it requires Linux (Note: The compile target is embedded!). I PRed an update to the build instructions, but it was rejected.

For all of these code bases, there is minimal or no documention: Neither guides, nor code comments. The functions, structs, fields, etc have no descriptions of their purpose or use. The modules, where you would expect a description of their purpose and use, instead includes the same license text at the top.
No jest, I just recalled this formulation incorrectly as being tail-recursive. Thanks for reminding me.
There are different rules for flying in an airshow [1]. Here's a very crude summary.

There's a designated area where the aircraft do their show in and there are not supposed to be spectators in that area.

Airshow craft can fly over spectator areas but not when doing anything dangerous and if they are high enough.

The US actually has some of the most stringent airshow safety rules in the world, which is why most of the time when there is an accident that kills a lot of spectators at an airshow it is not in the US. Plenty of pilots have been killed in US airshows, but the shows are carefully planned so that if something goes wrong the planes should crash away from spectators.

I don't know if drone shows are subject to the same rules.

Very true, and car longevity has been steadily increasing. Although, I don’t think the bulk of them failures are attributable to “rotting body panels”. I remember when a car with 100k miles was considered essentially dead, whereas more drive trains routinely last twice that long.
